System for quickly transferring data

Abstract

Data storage systems and methods for writing data into a memory component and reading data from the memory component are disclosed. By utilizing a high-speed data controller, the systems and methods transfer data at a fast data transfer rate. In one implementation, the memory component comprises a memory controller for managing data within the memory component. The memory controller comprises the high-speed data controller and a data manager. The data manager comprises a compression / decompression engine that compresses and decompresses data and a storage device interface.

AI Technical Summary

Benefits of technology

[0006]The present disclosure includes a data storage system for quickly transferring data between a host device and memory. One embodiment of the data storage system comprises a memory controller, which manages data within a memory component. The memory controller includes a data controller having parallel outputs, a data buffer connected to the data controller, and a data manager. The data manager may further comprise a compression / decompression engine and data and control outputs connected to memory.

Problems solved by technology

Although many memory cards provide large volumes of memory, the data transfer rate for storing large files into memory and retrieving files from memory are sometimes rather slow.

Existing memory cards are not capable of such transfer rates.

Although the pictures may be stored on a 512 MB memory card, with a slow data transfer rate, it may take up to 20 minutes to upload the pictures into a computer.

However, because of the slow data transfer rate into the non-volatile memory devices, data may get backed up in the data buffers, preventing the user from storing additional information until the data is eventually stored in the non-volatile memory.

Another problem with this solution is that SRAM and DRAM are relatively expensive and tend to drive up the cost of the host devices.
